PKG_CHECK chokes in bitbake

[Dan-Azure]

Hey, there.

There's a line in configure.ac called

PKG_CHECK_MODULES(SSHFS, [fuse >= 2.3 glib-2.0 gthread-2.0])

My bitbake chokes on it and gives a syntax error. I don't know if it's a version compatibility issue or wot, but I find that all my problems vanish if I change the line to

PKG_CHECK_MODULES([SSHFS], [fuse >= 2.3 glib-2.0 gthread-2.0])

Just wanted to mention it.

Hello.

I've pulled latest version (via git clone) and this problem occurs again: no extra quoting, syntax error.

Here is an output:

./configure: line 3796: syntax error near unexpected token `SSHFS,'
./configure: line 3796: `PKG_CHECK_MODULES(SSHFS, fuse >= 2.3 glib-2.0 gthread-2.0)`

Quoting this line with square braces (like in example provided by Dan-Azure) doesn't solve an issue.
Getting tag sshfs_2.8 as ZIP archive doesn't solve an issue as well. Did I miss something?
System is RHEL6, compiler is gcc-4.4.7, fuse version is 2.9.4.
If more information is needed I'm glad to share it. Thanks in advance.
